Definitions

  • the present invention relates to a frame for holding an image, suitable for decorative or marketing purposes.
  • the frame is foldable to enable efficient storage and handling.
  • Frames for decorative or marketing purposes are commonly used in a variety of different fields, such as interior decorating, marketing at fairs and the like, and displays for advertising.
  • a frame is made from four frame portions that are joined by four corner portions to form a completed frame.
  • the mounting and dismounting often requires tools such as wrenches or screw drivers.
  • a picture is applied to display information, an image or a marketing or advertising message.
  • the picture is sometimes printed on a canvas having an outer edge with a silicon strip attached to allow the edge to be inserted into a slot along the edges of the frame.
  • a foldable frame this presents the problem that the image is distorted during folding and storage through stretching of the canvas in the folded position or during the folding procedure, making it difficult or impossible to mount the frame again with the picture still attached and achieving the same look and feel as before the frame was folded.
  • a foldable frame for holding an image, the frame comprising four elongated frame portions, each having a first end and a second end, and further comprising four corner portions, two of which being of a first corner type and the other two being of a second corner type, wherein each frame portion is attached to a corner portion of the first type at the first end and a corner portion of the second type at the second end, so that a frame is formed where the corner portions of the first type are diagonally opposite, and wherein the corner portions of the first type are pivotable about a first axis and the corner portions of the second type are pivotable about a second axis and a third axis, respectively, the second axis and third axis being parallel to each other and essentially perpendicular to the first axis.
  • the frame can be folded to a small and compact packet that can be placed inside a storage bag and be transported and handled without risking damage. This facilitates transport as well as storage.
  • the first axis extends diagonally across the frame and through the corner portions of the first type and wherein the second axis and third axis are essentially perpendicular to a plane formed by the frame.
  • the second axis and the third axis are arranged to essentially coincide after the corners of the first type have been pivoted so that the corners of the second type are adjacent to each other. This further facilitates the pivoting of the corners of the second type and also decreases the size of the folded frame.

  • a locking pin can be inserted into the corner portions and prevent folding of the frame while the pin is in place.
